Heated bed not heating

I have a strange issue on my V-CORE3-300.

I replaced my Octopus v1.1 F446 with a new board (also v1.1 and F446, checked and double checked) and steppers. This as there was an issue with multiple steppers or the board, which caused Klippert to not even load the firmware.
After replacing board and steppers, they work great, but my bed is not heating anymore. Already replaced the SSR, but that did not solve it.
When heating the bed both the LED on the Octopus and the SSR light up, but nothing happens, just a "heater_bed not heating at expected rate" error after about 30 seconds. Also tried with another 230V heated bed and thermistor I had lying around, and same issue.

Checked all jumpers and they are the same as on the old board.

Which does point to some kind of configuration issue, but not sure what. Checked the settings in

RatOS.cfg

RatOS.cfg

and consequently

RatOS/printers/v-core-3/v-core-3.cfg

RatOS/printers/v-core-3/v-core-3.cfg

and

RatOS/printers/v-core-3/300.cfg

RatOS/printers/v-core-3/300.cfg

and

heater_pin

heater_pin

is set to PA1, to which it was and is connected on the board.

Literally moved the cables and plugs one-by-one from the old board to the new one.

Also used a multimeter to confirm voltage and such from the power supply and that all seems to be fine. The extruder heater is working just fine.

What can cause this (configuration) issue after replacing only the board?

Hope somebody can point me in the right direction or help me troubleshoot this.

Solution

Found the issue. The heated bed itself. Checked everything again and also used a light bulb to check if it lit up, and it did. Also tried with the other heated bed again and (I found out I connected it wrong earlier
